Hi All,
On my Ulster Rep, I currently have a steel cowl and cycle wings. The wings bolt directly to the sides of the cowl, apparently with no ill effects(no cracks or distortion). However, I have a new brass cowl. I have heard that it is advisable to fit a stiffener which arcs over the fan blade and stiffens the cowl and was designed for the 65. Is it advisable to fit this or would simple backing plates behind the wing fixing work as well? In such a case, they won't stiffen the cowl across but would stiffen the are of the fixing. If I need the 65 part, I've heard that Rod Yates makes them. Is he available by email or only phone?
